What the result means
Primary does not always mean physical left.
Web browsers report logical button roles. A left-handed operating-system setting can swap the primary and secondary physical buttons, so BeanNest labels the roles instead of making a hardware assumption.
Wheel numbers need their unit.
A browser can report wheel deltas in pixels, lines, or pages. The test shows the browser's unit beside the latest X/Y values instead of turning unlike units into a fake universal score.
Your movement data stays local.
BeanNest does not upload mouse button details, pointer coordinates, movement deltas, wheel deltas, click intervals, hold duration, or the local event history. The crosshair position is an ephemeral visual aid inside this page.
Why does a side button navigate or not appear?
Mouse software and browsers can map Back/Forward before a page receives a cancelable event. BeanNest suppresses defaults only inside the test pad when the browser exposes them, so testing another browser or reviewing your mouse-driver mapping can help.
What does the double-click count mean?
It counts the browser's dblclick events. The displayed interval between recent primary clicks is only a clue; it is not your operating-system double-click threshold and it is not hardware latency.
Can this measure DPI or polling rate?
No. This page is deliberately focused on reliable browser-observed button, wheel, movement, and hold behavior. DPI calibration, USB polling claims, and hardware latency need different measurement assumptions and are not certified here.
Can I test with a touchscreen?
The page remains readable on a phone, but touch and pen input are not counted as mouse presses. Use a mouse or trackpad for the active diagnostic.
